I have a 225 gallon 72x24x30 high. I have 4 uri VHO bulbs (72" 165watt each) 2 blue and 2 white. I am running 2 icecap 660 ballasts so I can add one more bulb to each one if need be. I have 300+lbs of live rock and a shallow sand bed. My water parameters are amm=0 nitrites=0 nitrates <5.

Can I keep any corals/anemones with this set up? My canopy has limited space so I don't really want to add MH but if they are necessary I can rebuild my canopy if need be.

I'm guessing if you're talking about URI lamps, you could have 3 of the White 50/50 bulbs, 1 Aquasun, and 2 of the Super actinics. That would be a good combo.
I've got 2X36" of the White 50/50 and 2X36" Super actinic and 2X12.5" actinic PCs on my 92-gal. It has a lot blue color, but that's what i like. That's why I suggested adding the Aquasun lamp.
